Gila robusta Baird and Girard 1853—Roundtail Chub

Van Devender and Worthington (1977) tentatively reported this fish on the basis of a vertebra from the 60-70 cm depth of Howell's Ridge Cave. Presumably this reflects permanent water in nearby Playas Lake, which has internal drainage. Playas Lake currently holds water only intermittently. At present, the nearest approaches of this medium-sized fish are in the Gila River drainage to the north and the Rio Bavispe to the southwest (map of current distribution).
